What I thought would be very quick and easy, to install Windows 7 on Virtual Box, led me having to do some googling after getting the error:
Windows Boot Manager Windows failed to start. A recent hardware or software change might be the cause. To fix the problem...... Status: 0xc0000225 Info: An unexpected error has occurred.
When creating the VM in VirtualBox it asked me for the guest OS which I choose “Windows 7”, thinking that by doing this, it would all work!
To resolve this error, thankfully its a simple fix:
- Power Down the Virtual Machine
- Go to the Settings of the Virtual Machine
- Under “System” tick on “Enable IO APIC”
This also solved my problem installing Server 2012 RC on Virtualbox. Thanks.
Likewise with Server 2012 Foundation and Essentials full release – Thanks a million!
